Magtrol Rotary Transmitters are used for signal transmission
of transducers on a rotating part (e.g. engine shaft)
to a stationary system (measuring instrument or PC). They
are exceptionally well-suited for the transmission of
low level electrical signals, such as those from thermocouples,
extensometer gauges and strain gauges, as well as transducers
to measure oscillation and acceleration. RS Transmitters
can also provide the power supply signal to each transducer.

Magtrol's RS Series Rotary Transmitters do not use slip
rings and are therefore arc-free, making them superior
to all other rotary transmitters that use rings, brushes,
wire loops and similar devices. Easy to use, installing
RS Transmitters is as simple as connecting a cable. They
require no power supply, batteries, software or parameter
setup in order to operate. Standard models have a speed
range of 0 to 20,000 rpm and a high-speed version (up
to 40,000 rpm) is available.
